How many times, correct to the nearest whole number, will a man run round a circular track of diameter 100m to cover a distance of 1000m?

In terms of distance, a circle has a total distance or perimeter of 2πr or πd

Where r is radius and d is the diameter

So perimeter = \(\frac{22}{7}\) x 100

= 314.2857m

To cover a distance of 1000m, he is going to round the circular track for \(\frac{1000}{314.2857}\) = 3.18

\(\approxeq\) 3 (to the nearest whole number)

There is an explanation video available below.
